Abstract

Liquid ring compressors and pumps using a ferrofluidic ring liquid are disclosed there being electrical coil means disposed around the compressor or pump casing to induce a field in the ferrofluidic ring liquid causing that liquid to form a rotating ring within the casing to drive the rotor.
